Good filter for sunset?

With 58mm threads, whats your favorite filter to use for sunsets?
I dont mess around with filters too much, but I'd like to experiment.

NONE! They create a lot of ghosting and flares when pointed into the sun. I always take my UV off when taking sunsets. You can simulate filters in PP if you want.

No need for filters. This is, mostly, a holdover from B&W film days.

Don't need a filter, but if you are set on getting one, a UV filter would not be a disaster.

3-stop reverse graduated neutral density filter. Pay no heed to the filter naysayers... But ditching the UV or other "protective" filter goes without saying.

I didn't intend to include ND filters, in all their variations, in my comment. Also a polarizer and, if one is so inclined, (I am not) some sort of "protective" filter. Everything else, pffft.

thats what I was asking about.
ND filters. for sunsets.


I dont know what to look for though.

I like the images that look like this. Do I have to buy a purple GND to get that effect though? I've never actually seen a purple sunset but I like the look of it.

Looks to me like it was done in PP.

But for sunsets in peticular- which GNDs and CPLs are your favorites?

My most often used are either 3 or 2 stop Cokin P ND grads
